Gallo Campground is the place to stay to visit the Chaco Canyon ruins. It's very small and very difficult to get to given the state of the dirt roads through tribal lands. Unless an RV is designed for this type of environment, it would be better to stay elsewhere and drive in with an AWD vehicle. The location is remote so be sure to bring drinking water and all the food you need. There is very little water in the region, so the facilities are limited. There are bathrooms and a place to wash dishes, but nothing else. The camp hosts are kind and helpful. We were able to view the Milky Way on one night of our stay. The visitor center is nearby, but most of the artifacts have been removed for safe keeping as there are issues with the building. They have an excellent selection of books on Chaco to purchase. The trails are well kept and closely watched by the rangers due to the sacred nature of the fragile structures. It was well worth any inconvenience for the privilege of seeing this amazing, sacred place.
